What are your opinions of these high-flow air filters? I will be staying with the OEM air box and wondered which of these three is number one? All feedback is appreciated.

I've only heard of the BMC. Seems pretty impressive, though don't know how much more effective it is than the K&N. The $75 price tag is also kind of painful.

JJ...
Agreed...perhaps to painful with no support data. What about the oiled foam filters(e.g. Amsoil or True Flow)? Any opinions?

Not sure about the oiled foam. Amzoil advertises as though theirs is extrememly good at filtering out dirt and allowing for a very good airflow. I bought one for the wife's Subaru and installed it. Not sure about it for a "more critical" application like MY car.
